Crying is the production of tears by humans as a response to intense emotional reactions. This biological behavior serves as a way for people to express emotions such as emotional pain, happiness, anger, empathy, and many other feelings. Crying is considered a behavior unique to humans, and it produces three main types of tears: basal tears, reflex tears, and emotional tears.

• Basal Tears:

These are tears that constantly lubricate, protect, and help remove foreign particles from the eyes. They serve to protect the surface of the eyes and prevent them from drying out.

• Reflex Tears:

These tears are produced in response to irritants such as foreign particles in the eyes, smoke, or sharp odors. Reflex tears are produced automatically by the body to protect the eyes.

• Emotional Tears:

These tears are produced when humans react emotionally, particularly in response to strong feelings such as sadness, happiness, anger, or empathy. Emotional tears serve the function of expressing emotional burden and providing relief.

Why Does It Occur?

The evolutionary origin of crying is related to animals giving vocal responses to ask for help from their environment. In humans, this behavior emerges as a reaction to strong emotional stimuli. In infants, the lacrimal glands are not fully developed, and it is through crying that these young individuals demonstrate a behavior of seeking help from their environment. In adults, emotional tears can be triggered by a wide range of emotions, including physical pain, relationship pain, empathetic crying, social pain, and moral or sentimental feelings.

How Does It Occur?

Crying is a behavior that emerges when humans experience intense emotional reactions, triggered by the interaction of specific regions in the brain. This interaction triggers various psychological and physiological responses.

The Onset of Crying

Crying typically arises as a response to an emotional stimulus, stressful or painful situations, an empathetic reaction, or significant relief. The human brain produces emotional responses to environmental stimuli, and the onset of crying is based on the management of these emotional responses by the brain.

Events in the Brain

The process of crying is controlled by the limbic system, which is the brain region responsible for managing emotional functions. This region activates in response to an emotional stimulus.

Limbic System

The limbic system is the brain area that processes emotional responses, and structures such as the amygdala and hypothalamus play an important role here.

• Amygdala: This area processes and interprets strong emotional states like fear, sadness, and anger. It is the primary structure that triggers emotional responses like crying.
• Hypothalamus: This region manages the body's autonomic functions and transmits signals of stress to the body. When the brain detects pain or stress, the hypothalamus can reflect this to the body and initiate tear production.

Pons Region

The pons region in the brain plays a crucial role in coordinating the process of crying. The pons connects emotional responses with the physiological changes that occur in the body. It is the center that initiates physical responses, including tear production.

Autonomic Nervous System

The autonomic nervous system controls the physiological aspects of crying. Specifically, the sympathetic nervous system activates in stressful situations, which increases heart rate, tenses muscles, and generates the emotional burden leading to crying.

On the other hand, the parasympathetic nervous system sends relaxation signals to the body, aiding in the calming process during crying.

Tear Production

During crying, tear production is carried out by the lacrimal glands. Signals from the pons area of the brain are sent to the lacrimal glands, leading to an increase in tears in the eyes.

Chemical Reactions

During crying, chemicals like oxytocin and endorphins are released in the brain. These chemicals enhance the relaxing and healing effects of crying:

• Oxytocin increases feelings of bonding and trust, promoting relaxation.
• Endorphins have pain-relieving properties and improve mood.

The release of these chemicals demonstrates that crying not only provides emotional relief but also contributes to physical healing.

Crying as a Process

Crying arises from the interaction between the limbic system and the autonomic nervous system in the brain. Structures like the amygdala, hypothalamus, and pons trigger the physiological processes of crying and enable tear production. Crying creates chemical changes in the body, leading to both psychological and physiological relief. Understanding this complex interaction helps explain the emotional and health benefits of crying.

Effects on Health

Crying has been shown to have numerous positive effects on health. It serves as a mechanism for expelling stress hormones and toxins from the body. Emotional crying helps to relax the body, bringing balance to both physiological and psychological states. Studies have shown that crying can strengthen the immune system, improve heart health, and help reduce hypertension. Additionally, emotional release during crying offers a positive aspect, as it provides an opportunity to release the emotional burden of an event.

Positive Effects

The positive health effects of crying have historically been recognized. Since ancient Greek and Roman times, crying has been thought to serve a purgative function, and this view has been accepted from a psychological perspective today. Crying helps to expel stress hormones and toxins from the body. This process triggers the release of oxytocin and endorphins (endogenous opioids). These chemicals alleviate both emotional and physical pain, creating a general sense of well-being.

Another positive effect of crying is the strengthening of social bonds. When people cry, the empathetic responses of others provide emotional support and closeness. Research has shown that emotional crying enhances social connections and helps establish stronger bonds between individuals.

Negative Effects

Excessive crying or the continual triggering of certain situations can lead to emotional imbalances. Chronic crying may be a sign of psychological conditions such as depression. Additionally, crying that is not done appropriately in social settings may lead to feelings of embarrassment or exclusion. Social norms that suggest men should not cry may prevent emotional expression in men and create emotional health issues.

Some individuals, due to conditions like depression, may be unable to cry. This inability to express internal emotional pain may lead to emotional blockage, further deteriorating psychological health.

Psychological and Physiological Effects

Crying not only provides psychological relief but also enhances emotional function. Psychologically, crying allows individuals to express their pain and sadness, leading to emotional discharge and recovery. Physiologically, crying calms the body and regulates heart rate. Additionally, hormones such as prolactin released during crying help reduce stress and promote recovery.

The emotional crying centers in the brain guide individuals to form healthier bonds with their environment. These connections play a key role in emotional healing and, with social support, enhance the healing effects of crying.

Crying is a natural response that provides emotional relief and purification. Emotional tears play a significant role in expelling stress and promoting relaxation in the body. Crying enhances social bonds and increases empathy, contributing to both psychological and physical healing. However, excessive and uncontrolled crying may indicate psychological health issues and may require professional help.
